Marine or RV house bank. Very heavy battery. It requires two people struggling down the dock because each one is carrying about 82 lbs a piece. It lasts quite a long time. If it is being used as a house bank and you want to save your back, you might consider 2 UPG-GC2 6v batteries (our Part # UPG-45966) in Series which will actually give you slightly less amp hours, but you won"t get a hernia, and they can ship UPS.

This state-of-the-art lead-acid battery is the valve-regulated type (called sealed, AGM or maintenance-free), which fixes the acid electrolyte in an absorptive fiberglass mat. The advantage of this design is that the battery needs no water additions, can be operated in any position, and can be used in close proximity to people and sensitive equipment.
